Bug 555960 - Nested structs and unions (generation portion)

Patch from Andreas Rottmann <a.rottmann@gmx.at>.

	* tests/scanner/utility.h (UtilityTaggedValue): Make the union
	member anonymous.
	(UtilityByte): New union typedef with an unnamed struct in it.

	* giscanner/transformer.py (Transformer._create_struct): Create
	unnamed structs for symbols with a None ident.
	(Transformer._create_union): Likewise.

	* giscanner/girwriter.py (GIRWriter._write_record): Allow name
	being None.
	(GIRWriter._write_union): Likewise.

	* girepository/girparser.c (start_struct): Allow a NULL name for
	non-toplevel structs.
	(start_union): Likewise.

	* tests/scanner/utility.h (UtilityTaggedValue): New struct
	typedef, which has a nested union member.
	* tests/scanner/utility-expected.gir: Adapted.

	* giscanner/transformer.py (Transformer._create_member): Create
	struct/union members if appropriate.
	(Transformer._create_struct, Transformer._create_union): Allow for
	structs/unions without a C type.

	* giscanner/glibtransformer.py (GLibTransformer._resolve_field):
	We don't need to resolve non-typef'd
	(GLibTransformer._resolve_field): Add cases for non-typedef'd
	struct/union "fields".

	* giscanner/girwriter.py (GIRWriter._write_record): Allow for
	records without a C type.
	(GIRWriter._write_field): structs and unions may appear in places
	where fields do.
